   Consequence: Legal injunctions, product seizures, and liability for damages.
   Mitigation: Conduct IP due diligence before sourcing; require suppliers to warrant non-infringement and provide design freedom-to-operate (FTO) opinions.

2. Weak IP Clauses in Contracts
   Pitfall: Sourcing agreements may lack clear ownership language, allowing suppliers to claim rights over co-developed or customized designs.
   Consequence: Loss of control over proprietary thermal management technology and barriers to future innovation.
   Mitigation: Include explicit IP assignment clauses stating that all designs, tooling, and improvements developed for your product belong to your company.

3. Insufficient Protection of Technical Specifications
   Pitfall: Sharing detailed CAD files or performance data without NDAs or restricted use agreements exposes sensitive engineering know-how.
   Consequence: Risk of reverse engineering or unauthorized use by the supplier in competing products.
   Mitigation: Implement tiered information sharing, use confidentiality agreements, and watermark or encrypt design documents.

4. Tooling and Fixture Ownership Ambiguity
   Pitfall: Suppliers often retain ownership of molds, jigs, and test fixtures used in production, even when fully paid for by the buyer.
   Consequence: Inability to switch suppliers quickly or duplicate production elsewhere.
   Mitigation: Ensure contracts specify that tooling paid for by the buyer is company property and must be maintained or transferred upon request.

Conclusion
